Sure is @bigcol .. Thetford chemicals you're looking at $20+ each for both lots.![]()
Only ever pay about $14 a bottle................
And.....just remembered....
The napisan stuff is ok to dump into septic tank when you return home. Other Thetford stuff is not.
The Thetford stuff is actually okay for the Septic, the Formaldahyde story is a furphy...........our septic has had heaps tipped in it and all is good, just don't go overboard with the Nappisan, too strong a brew will upset the bugs in the septic just the same as cleaning the bowl too much with strong stuff.
